Brain tumour symptoms vary
п‚·
Brain tumours may have a variety of symptoms, as different parts of the brain control different functions
and symptoms can vary depending on the tumor's location. Symptoms may include some of the
following:
•
headaches (strong enough to wake you up in the morning);
•
seizures in a person who does not have a history of seizures;
•
cognitive or personality changes;
•
eye weakness, nausea or vomiting, speech disturbances; or
•
memory loss.
Categories of brain tumours – primary malignant, primary benign and secondary
п‚·
Central nervous system tumours are tumours that arise in the brain, spine or meninges.
•
Primary brain tumours are further grouped into "benign" and "malignant" tumours.
 A malignant brain tumour is life threatening, invasive and usually rapid growing.
 A benign tumour consists of very slow growing cells, usually has distinct borders,
and rarely spreads.
п‚· Treatment and/or surgery is often effective, however, if a benign tumour is
located in a vital area of the brain, it can be considered life threatening.
 Primary brain tumours rarely spread outside the brain and spinal cord.
•
Metastatic (or secondary) brain tumours arise when cancer cells which begin growing
elsewhere in the body (ie lung, breast or other areas) then travel to the brain.
 All metastatic brain tumours are malignant since they begin as cancer elsewhere in
the body.
•
There are over 120 different types of brain tumours alone, of which some 40 are classified as
malignant.1
•
The location and grade of the tumour, the treatments undertaken and a range of other factors
influence the impact on the patient, their abilities and prognosis.
•
The term �brain cancer' is used by some including the statisticians and the term �brain tumour’
by others. Brain tumours may spread within the central nervous system but rarely outside.
•
BTAA uses the term �brain tumour’ to refer to all tumours of the central nervous system.
Causes unknown
п‚·
п‚·
The causes of brain tumours are unknown; they are not preventable by any known lifestyle changes;
early detection is not possible.
•
There are no screening tests for brain tumours.
It is possible that each type of brain tumour has different causal factors, and its degree of severity or
malignancy (the grade of tumour), its location within the brain, the size of surrounding tissue mass
affected by the tumour, whether it is diffuse or defined, are considered when classifying , treating or
researching brain tumours.
Treatment and support
п‚·
п‚·
Cause complex health issues and may require intervention from numerous specialities.
A range of tests may be performed to diagnose brain tumours, including neurological examination by a
doctor, a CT-scan, MRI and biopsy.
•
Better treatment leads to longer life expectancy and better neurological outcomes.
•
Critical shortages in health professionals best able to manage health of brain tumour patients.
•
Brain tumours (and treatment side effects) may impair decision making, mood and judgement.

Summary statistics
 Brain tumour research funding is low compared to the burden of the disease – along with lung cancer
and mesothelioma, bladder cancer, pancreatic cancer, lymphoma and cancers of unknown primary site.2
п‚· There are an estimated 5,600 living Australians who have been diagnosed with primary brain tumours
sometime in the previous 26 years (when national records began).3
•
This includes 2,444 people diagnosed in the past 5 years.4
 Statistics for the period 2006–2010 show people with primary malignant brain tumours had a 22%
chance of surviving for at least 5 years compared to the general population.5 Five year survival was:
•
slightly higher for females (24%) than for males (20%).6
•
highest for those aged 0–39 at diagnosis (59%) and dropped steeply with age thereafter. 7
•
less than 5% for those aged 70–79 at diagnosis. 8
п‚· There were more than 1,6009 new cases of primary malignant brain tumours in Australia in 2010,
including around 90 in children10. In addition it is estimated that, annually, there are more than 2,000
new cases of so-called benign brain tumours that may cause disability or (rarely) death.11
п‚· There were 1,247 deaths from primary brain tumours (both malignant and benign) registered in 2010.12
•
Primary brain tumours were the second highest cause of death for children aged 1 – 14 years
from all causes – after drowning/immersion; and the highest cause of cancer death for this age
group (an average of 31 deaths per year over the period 2008 to-2010).13
•
Primary brain tumours were the highest cause of cancer death in persons aged less than 40
(an average of 111 deaths per year over the period 2006 to 2010). 14
 Leading cause of cancer death in males aged less than 45 (an average of 93 deaths
per year over the period 2006 to2010). 15
 Leading cause of cancer death in females aged less than 35 (an average of 32
deaths per year over the period 2006 to 2010). 16
п‚· Largest lifetime financial costs faced by households of any cancer type, at $149,000 per person, and the
highest lifetime economic cost of any cancer type, at 1.89 million dollars per person.17
 In 2008–09 there were 5,037 hospitalisations, with an average length of stay of 11.9 days — a longer
average length of stay than for any other cancer type.18
 Primary brain cancer accounted for 2.3% of all palliative care hospitalisations in 2009–2010, the 7th
highest of the cancers.19
